Benefits of technology

The patent is about a method for making elongated profiled parts. The new method simplifies the process, improves reproducibility, uses less energy, is cheaper, and produces durable parts. It also reduces the risk of warping and improves energy and cost efficiency. The method involves trimming a flat strip before formed, so plastic deformations don't affect the trimming, and the method allows for easier and more accurate trimming and forming. Additionally, equal trimming at both edges of the flat strip reduces the risk of warping.

Problems solved by technology

In addition, for the offsetting of the longitudinal sections, the embossing tools require comparatively powerful embossing forces, thus reducing the energy efficiency of the method and along with an increased tool wear, increasing the method costs.

Embodiment Construction

[0031]FIGS. 1, 2, and 3 show examples of an elongated profiled part 1 produced with the method according to the invention. This elongated profiled part 1 has essentially two different longitudinal sections 2, 3 with a U-shaped profile—which is shown in FIGS. 2 and 3. The middle longitudinal section 3 is offset relative to the adjacent longitudinal sections 2 in a direction perpendicular to the longitudinal direction 4 of the profiled part 1. FIG. 1 shows the maximum offset 5 in the direction perpendicular to the longitudinal direction 4 of the profiled part 1. Starting from a bottom path that is in the middle and parallel to the bottoms 6 of the longitudinal sections 2, the bottom 7 of the longitudinal section 3 adjoins the bottoms 6 of these longitudinal sections 2 by means of inclined bottom paths. This bottom path shown for the longitudinal section 3 is intended as an example, any bottom path is conceivable, for example rectangular, V-shaped, etc.; it is enough for the invention ...

Abstract

An apparatus and a method for producing an elongated profiled part, in which a profiled strip is produced from a flat strip by rolling and the profiled strip is embossed in sections, by means of which at least one longitudinal section of the profiled strip is offset relative to at least one other longitudinal section in a direction perpendicular to the longitudinal direction of the profiled strip, and with which method the strip is trimmed in such a way that, after the embossing, the longitudinal sections that are offset relative to each other have different cross-sections. In order to increase the reproducibility of the method, before the profiling, the flat strip is trimmed in such a way that by means of the embossing of the trimmed and profiled strip, the longitudinal sections that are offset relative to each other have different cross-sections.

Description

FIELD OF THE INVENTION[0001]The invention relates to an apparatus and a method for producing an elongated profiled part in which a profiled strip is produced from a flat strip by rolling and the profiled strip is embossed in sections, by means of which at least one longitudinal section of the profiled strip is offset relative to at least one other longitudinal section in a direction perpendicular to the longitudinal direction of the profiled strip, and with which method the strip is trimmed in such a way that, after the embossing, the longitudinal sections that are offset relative to each other have different cross-sections.BACKGROUND OF THE INVENTION[0002]In order to produce an elongated profiled part with a vertical offset and different cross-sections over the course of the profile, it is known in the prior art (EP1344583B1) to profile a flat metal band, then to emboss it in sections, and then finally to aim it. By means of the sectional embossing, two of the longitudinal sections...
